EF 400 f/2.8 L IS USM - Instruction manual

Can anyone help me please. I recently bought a used 400 2.8, but don't have the operating instructions for it. If anyone has a copy or could make a copy for me, I would be extremely greatful. Please PM me if you can help in any way.

Many Thanks in advance.

Regards,

Barry.

I do have to ask though, what about the lens requires a manual? Isn't it pretty straightforward...?

I agree, barryvj171 what are you having issues with or what do you want to know?

The manuals are usually pretty sparce besides info on IS and such which people can answer on here if you ask what you are curious about

You guys are so funny!

Barry, I don't know how easy it is to download a manual for a lens. You can try Canon't website, find the lens, and go to Support and ask them directly, or you can try a Google search with different search criteria, or you could ask here, which is obviously an ill-advised idea!

Seriously, though, lenses are almost plug and play. They have switches: AF/MF, IS ON/OFF. IS Modes. Focus Presets. Those things have specific functions and if you ask us we can tell you. Some things may be lens specific, like whether or not you can manual focus while in autofocus, and you can ask, although that feature is most likely on your high-end lens.

In general, you start out with AF (auto focus), IS on (at 400mm I think IS is good even when using a tripod, but other people think differently so try different settings) and the IS mode is set to 1 for still shooting or 2 for panning a moving object. I often forget to switch between the two.

Aside from those things the most vamuable thing to find out is if you can manually focus to fine-tune autofocus: press half-way on your shutter button and while holding the button down try turning the focus ring. Does it change focus? If so, you can combine the two.

Two things I forgot: First, minimum focus distance. You can figure this out by getting four feet or so from something and then backing up until you get focus lock. Second is focus range: you will have a switch that will likely vary from a close range distance to a long range distance (with probably a stop with a narrow range distance). This is a helpful switch, because if you tell the lens that you only want to focus on things that are at least 10 meters away the lens will frankly refuse to focus on your dog which is only 4 meters away. If, on the other hand, you tell your lens that you are willing to focus on anything from 3 meters away to infinity, your lens could focus on a branch 10 feet away while you're trying to catch that once-in-a-lifetime shot of Britney Spears...and that would really suck...

Seriously, IS there a manual for lenses? Did'nt know that.

My 17-55 I got today had one and it was about as thick as my flash and 40d manual! I guess I should have at least peeked inside it and see why they killed 3 trees printing it.

Somebody is jealous...

Hi Tony,

I really appreciate you taking the time to write something sensible, not like the other facetious comments from boneheads above. It was just a simple request to see if anyone could copy one for me. To date, I don't own any IS lenses. I only have 16-35mm f/2.8 II, 85mm f/1.2 II, 135mm f/2, EF 300mm f/2.8 (non IS) and now the 400 f/2.8 with IS. I am not familiar with how the IS works, hence my request to find an instruction manual.

Idiotic comments like "Put lens on camera, Point lens at subject, Press shutter button" are probably made by people who don't know which end of the camera to look through.... why do you even bother to post comments such as this ??

I was under the impression that this forum was to help people with developing their photographic skills, for those who know some, to help those who don't and that want to learn. Also to bounce ideas around and to make constructive comments and criticisms, so that we can all develop our own identities and styles; not to make stupid comments and show how truly ignorant you really are..... well done mate, you just did that !!

Any other sensible comments would gladly be appreciated. Thanks !!

Regards,
Barry.

they are just trying to be funny in a 'smart-ass' sort of way... no need to get offended.

Canon's website(s) can be difficult to navigate.. I'm almost positive there is a downloadable PDF form of each lens' manual on Canon's official site.

^^ I may be wrong... says here it's not available for DL...

Thanks, yeah, I did look on the Canon website, AU, USA and Europe, but no PDF's there at all....

There are a few people in this thread who need to re-read the forum terms of use:

https://photography-on-the.net/forum/rules.ph​p

Specifically:

1. If you know an answer to a question either answer it or say nothing. Giving newbies blunt answers like "search the forum" is not allowed - please use the typing effort to giving the answer instead. Or just give the link to that post you wished the newbie should have searched for. Respect newbies - you were a newbie once.

it's only a matter of you willing to answer a question or not.
yeah, we all know google.com. but before someone put such ignorant comments, they should consider that the thread starter had already googled the web but couldn't find anything, maybe?

barryvj171: maybe you can email canon rep. and see if they can do anything to help you
